However, service performance and reliability of those existing apparatuses are rather unstable. Although we have some other latter inventions created with a comparatively better in service performance and use reliability, however, under the present techniques it requires a cost to manufacture.

[0005] Worsen still; it is very difficult for consumers to put those apparatuses to use due to the complication of designs and assembly methods. Moreover, the field of application of those existing liquid spraying apparatuses are all having limitation when it comes to their corollary sanitary apparatuses. In short, the existing liquid spraying apparatus can hardly meet the market demand.

[0012] a inlet pipe with one end penetrated connected with the spraying nozzle and the T-sharp pipe;

[0013] one-way valve located within the inlet pipe;

[0014] a gas pipe extending from the T-sharp pipe;

[0015] a liquid container with at least one end mounted on the bottom portion of the T-sharp pipe;

[0016] a gas pipe extended from the T-sharp pipe to a gas bag, plastic hose is adopted for the gas pipe, which links up to the gas bag, down to one end of the T-pipe, one inlet of the T-pipe connects with inlet pipe of the liquid container and its outlet links to the one-way valve;

[0018]FIG. 2 is the structural schematic diagram of the application example after the apparatus is installed in the sanitary apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] As illustrated in FIGURE (1), the liquid spraying apparatus is composed of spraying nozzle (1) and its joint one-way valve (2), gas bag (8) and its joint gas pipe (7), liquid container 4 and its built-in inlet pipe (5), and the inlet valve (6), which connects with inlet pipe (5); spraying nozzle (1), gas bag (8) and liquid container (4) are linked up through the T-pipe (3).

[0020] Plastic hose has been adopted for the gas pipe (7), which links up to the gas bag (8) and down to the one end of T-pipe (3), according to the liquid spraying apparatus.

[0021] One inlet of the T-pipe (3) links to the inlet pipe (5) inside the liquid container (4), and the outlet connects with the one-way valve (2), according to the apparatus.

[0022] Inlet pipe (5) links down to the inlet valve (5), according to the apparatus, gas bag is the elastic cavity body made of rubber, according to the apparatus.

[0023] The installation and operation of the liquid spraying apparatus is as shown in FIG. 2. The apparatus shall be fixed in the handle by connection with screws and handle tape. Hold the gasbag (8) for pressing and releasing. When the gasbag is pressed, the gas inside the gasbag shall push the one-way valve (2) through T-pipe (3) from the gas pipe (7) and then be exhausted out from the spraying nozzle. Meanwhile, the water inlet valve (6) shall be closed by the gas exhausted from water inlet pipe (5), and shall make the gasbag elastic and automatically respond. With the pressure of the gas, the alkaline liquid in the liquid container (4) shall push away the water inlet valve (6) and enter the water inlet pipe (5) from T-pipe (3). At the same time, the one-way valve (2) is closed and the alkaline liquid is absorbed into the gas pipe (7). When the gasbag (8) is pressed for the second time, the alkaline liquid in the gas pipe (7) pushes the one-way valve (2) through the T-pipe (3) owing to the pressure of the gas. The water inlet valve (6) is then closed and the alkaline liquid is forced to spray out from the spraying nozzle (1).

[0024] After the gasbag is released, the alkaline liquid is again absorbed into the gas pipe. By repeatedly pressing and releasing the gasbag, the alkaline liquid in the liquid container (4) shall be absorbed and sprayed out from the spraying nozzle through the water inlet pipe, T-pipe and the one-way valve. The alkaline liquid shall form a sector shape and be evenly sprayed on the surface of the object when it is being sprayed out.

[0025] This newly invented liquid spraying apparatus adopts liquid spraying principle based on pneumatic compression. The alkaline liquid and the cleaning water shall be sprayed out by pressing the gasbag. Therefore, it is very convenient to use such liquid spraying apparatus for cleaning floors, doors and windows. The apparatus can also be incorporated in various sanitary tools, with simple and easy installation and low cost. For example, it can be installed in wringing mop, glass eraser based on compressed spraying liquid and telescopic hair brush. Anyhow, it can be incorporated in all the sanitary tools.
